Chemicals inventory database

A list of substances that were subject to TSCA actions at the time of the 2006 Inventory was contained in Appendix C to the Instructions for Reporting for the 2006 Partial Updating of the TSCA Chemical Inventory Database. (Nov. 2006) [hereinafter 2006 Instructions]. However. EPA makes clear in that Appendix that the Appendix is intended to be only an information resource. The list should not be relied upon in lieu of relevant orders. Federal Register documents, or the Code of Federal Regulations. 

A manufacturer who makes twenty-six thousand pounds of a chemical, uses two thousand pounds for research and development, and sells the remaining chemical for industrial uses must report. The total amount of the chemical manufactured must be reported because the reporting threshold is exceeded. Questions and Answers for Reporting for the 2006 Partial Updating of the TSCA Chemical Inventory Database EPA Office of Pollution Prevention and Toxics Economics, Exposure and Technology Division, 84, Question 55 (Nov. 2006). 

A hazardous chemical list for each laboratory vsrill be maintained by the lab supervisor, wrho may update it periodically and make it accessible to laboratory personnel. The chemical inventory database wrill provide information regarding chemicals purchased and delivered to the labs and should serve as the basis for the hazardous chemical list. 

Chemical inventory system for Tier I/II information. Includes capacity to inventory quantity and location information. Contains database of 3100 hazardous chemicals. 

The USEPA must establish and inainlain a national toxic chemical inventory based on all Ihc release data submitted, wltich must be accessible by computer on a national database. 

According to the Toxic Chemical Release Inventory database (TRl), an estimated total of at least 49 million pounds of trichloroethylene was released to air from manufacturing and processing facilities in the United States in 1988 (TRI88 1990). The level reported in 1993 was 30.2 million pounds (TRI93 1995). The number of reporting facilities in each state and the ranges within which individual facilities reported their releases are shown in Table 5-1. The TRI data listed in this table should be used with caution since only certain types of facilities are required to report. This is not an exhaustive list. 

No information is available in the Toxics Release Inventory database for facilities that produce HDI because this compound is not included under SARA, Title III and, therefore, is not among the chemicals that facilities are required to report (EPA 1995). 

HDI and HDI prepolymers can be released to the atmosphere during spray applications of polymer paints containing residual amounts (0.5-1.0%) of monomeric HDI (Alexandersson et al. 1987 Hulse 1984 Karol and Hauth 1982). These substances could also be released to the atmosphere from waste streams from sites of HDI or polymer production. No information is available in the Toxic Chemical Release Inventory database on the amoimt of HDI released to the atmosphere from facihties that produce or process HDI because this compound is not included under SARA, Title 111, and therefore, is not among the chemicals that facilities are required to report (EPA 1995). There is also a potential for atmospheric release of HDI from hazardous waste sites however, no information was found on detections of HDI in air at any NPL or other Superfund hazardous waste sites (1996). Beeause of the relatively rapid reaction of HDI with hydroxyl radicals in the atmosphere an possible hydrolysis (see Seetion 5.3.2.1), significant atmospheric concentrations are not expeeted to oeeur exeept near emission sourees. 

No information was available in the Toxics Release Inventory database on releases of diazinon to air from manufacturing and processing facilities because these facilities were not required to report releases of this chemical prior to January 1, 1995 (EPA 1995a, 1995b). 

Provides toxicology data for more than 130,000 chemicals in four categories substance identification toxicity/biomedical effects toxicology and carcinogenicity review and exposure standards and regulations. Built and maintained by the National Institute for Occupational Safety and Health (NIOSH) as a segment of the Toxic Release Inventory database. Available online, CD-ROM and computer tape from NIOSH and from commercial database vendors.

Ethane is a flammable gas present in the exhausts of diesel and gasoline engines, municipal incinerators, and the combustion of gasoline. Inhalation and other exposures cause CNS depression in mammals. Ethane in liquid form results in frostbite,3 and the United States Environmental Protection Agency (USEPA) has listed it under chemical inventory and the test substance database. 

A chemical inventory is a listing of industrial chemicals manufactured in, or imported by, a country and is used primarily to distinguish between new and existing chemicals.14 It is basically a database created from information submitted to government authorities by manufacturers, processors, users, or importers. Depending on the country, the content of an inventory can range from the Chemical Abstracts Services (CAS) numbers or names of chemicals in commerce, to the amount produced and imported by specific location, to the amounts being used for different purposes. 

The non-confidential AICS can be accessed on-line via the NICNAS Web site. Alternatively, a request to search the AICS can be made to NICNAS. Furthermore, a search of the confidential section of the AICS can be requested but only through this mechanism. The AICS is also available on the Chemical Abstract Services Chemlist database or National Chemical Inventories (NCI) [4]. 

Jarvis-Patrick clustering has also been used to support QSAR analysis in a system developed at the European Communities Joint Research Center. " ° The EINECS (European Inventory of Existing Chemical Substances) database contains more than 100,000 compounds and has been clustered using 2D structural descriptors. That database also has associated physicochemical properties and activities, but the data is very sparse. Jarvis-Patrick clustering was used to extract clusters containing sufficient compounds with measured data for an attempt to be made to estimate the properties of members of the cluster lacking the data. For a few clusters, it was used to develop reasonable QSAR models. 

Contents Include overview of EPCRA requirements, reported chemicals, emergency planning and release notification, MSDSs, chemical inventories, data sources, TRI database searching, assessing chemical risks, and communicating with a non-technical audience. 

MACCS-II with its Customisation and DBMS Interface modules can be tailored to the chemical-scientific database needs of entire organisations or individual research groups. Customisation features allow MACCS-II to treat applications expressed in 1984 and many applications that go beyond those. These applications include interfaces with database systems, scientific programs, and scientific instruments that are used in regulatory reporting, laboratory information, and inventory systems. Examples of some applications are as follows. 

Each record in a chemical inventory c tabase generally corresponds to a single container of a chemical rather than merely to the chemical itself. This approach allows for a more logical correspondence between the records in the database and the chemicals stored in the laboratory. The following data fields for each item are probably essential in... 

A chemical inventory is a list of all the chemicals at a facility or lab. Today, such inventories are almost always located in a computer database. Why do you need an inventory It will keep you and others safe and secure. Inventories are used for ...
